OK,
Some progress .
Carbs cleared again and reinstalled.Still won't start.
Used Easy start spray.Still no go.
The plugs are wet and good spark.
However i have just checked the points.
One side is intermittently sparking the other set not at all.
Do i need to fit new points and condensers?
Cheers,
Dave

Yes they were solid as were the main jets and idea jets.
Just a thought, is there any jet holes in the brass fitting above the main jet that houses the needle

CB750 / Vacuum pipes on CB750FO

I have got to the stage of trying to start my bike which came as a box of bits. IT won't start.
Carb jets were all very blocked.Slides seized.
I have cleaned the carbs and all jets are clear and slides and needles running free.
All four float bowls are filling with fuel but fuel does not appear to be passing through jets around the needles.
I have a good spark and good compression.
I have attached a picture of two tubes that i believe just vent atmosphere.
However when i apply compressed air to open tube end it will not pass through to inside of carb.
The tubes are new.
I have twice stripped the carbs and checked jets and floats.
Any ideas greatly appreciated,
Dave.

Thanks for all the input.
The prices are crazy for the right one.

So ill see how that works!
